Why Are Radiographs Necessary?

It’s time for your six-monthly checkup and clean, but your dentist has recommended updating your dental radiographs. You may wonder, “Why? Didn’t we do them two years ago? Can’t you just do my exam without them?” The answer is no—we can’t perform a thorough exam without them. Radiographs help us diagnose infections, decay, and other issues such as bone loss or infections around the roots of your teeth.

Why Visual Exams Aren’t Enough

During your examination, we rely on our eyes, dry teeth, and good lighting to detect decay. However, we don’t have x-ray vision. We can’t see decay beneath fillings or between teeth. Radiographs allow us to catch these problems early, so we can create a treatment plan before issues become more serious.

Are Radiographs Safe?

Yes, radiographs are safe. The radiation exposure from a dental radiograph is similar to what you’d experience on a 1-2 hour flight. They’re safe for both adults and children, and even during pregnancy (though typically postponed until after birth). Dentists leave the room during the x-ray only because they perform many radiographs daily and want to minimize their exposure.

Types of Radiographs

There are various types of radiographs, each capturing different angles and teeth. Your dentist will explain which type is needed and how they’ll be taken. Most radiographs are digital, making the process quick and enabling us to diagnose issues promptly, so treatment can begin if necessary.

Regular Updates for Optimal Health

Dental health can change rapidly, which is why regular radiograph updates are essential. Depending on your risk of decay or periodontal disease, your dentist will recommend how frequently you need radiographs to monitor for any changes.
